Can acid destroy a diamond?
No, acids cannot dissolve diamonds, for the simple reason that a diamonds carbon atoms are too tightly packed together for the Hydrogen ions to be able to dissolve the substance.
Can you scratch a real diamond?
DIAMOND DON’T: The Scratch Test Yes, it’s true, diamonds are the hardest substance on earth, and can only be scratched by other diamonds. But if you’re doing the scratch test where you rub it against another stone or with sandpaper and it’s not a diamond, you’re only going to ruin the stone you’re scratching!
Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Can fake diamonds pass diamond tester?
A diamond tester will only test positive for diamond and moissanite. Synthetic moissanite has been used as a gemstone only since the 1990s, so if your piece is from an earlier era, it’s definitely a diamond if it passes this test!
